It's a f@*$ing hydra!
Haha :) . Yeah Google practices are strange. I understand that it works for their internal ~200mil. code base, but for others, for FOSS projects..?

I think I've had enough. I will start using CLP's bare interface. It's too annoying to keep up with google's strange notions of project management. -For example, were you aware that abseil maintainers strongly discourage maintaining a binary library and instead recommend building from source at head?? No wonder we can't get ortools from conan. It's a f@*$ing hydra!
Thanks for your conanfile, though. I'll push my latest version here soon. Maybe you see something there that can help you.
Cheers!
